In chemistry, iron(III) refers to the element iron in its +3 oxidation state. In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe³⁺. The adjective ferric or the prefix ferri- is often used to specify such compounds — as in "ferric chloride" for iron(III) chloride, FeCl3. The adjective "ferrous" is used instead for iron(II) salts, containing the cation or Fe²⁺. The word ferric is derived from the Latin word ferrum for iron.
